Abstract

A method for detecting critical transverse movements. The method includes the following steps: emitting a CW radar signal and generating radar data based on the received reflected CW radar signal with the aid of a radar device; ascertaining collision-relevant spectral ranges of the radar data as a function of an ego velocity of the radar device; ascertaining a time dependency of a relative velocity and of an object angle of an object by evaluating the radar data in the ascertained spectral ranges; and detecting a critical transverse movement of the object using the time dependency of the relative velocity and of the object angle of the object.
